Solution Overview

Problem

Existing technologies face challenges in ensuring consistent communication between devices that use different communication schemes, particularly when one device lacks the capability to process data received through a specific communication path, leading to incomplete or failed handovers and user awareness of authentication and setting processes.

Innovation Solution

An information processing device and method that decides a transmission target control target device based on process capability information acquired through a first communication path, allowing connection information to be transmitted to the capable device for establishing communication through a different communication path, thereby enabling seamless handover without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If connection handover specification is used, then automatic communication switching between different communication schemes is enabled, but user awareness of authentication and setting processes is required

Engineering Contradiction:
Improveautomatic communication switchingVSAvoiduser awareness of authentication and setting
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The patent introduces an intermediary device that mediates between the first and second control target devices. This intermediary acquires capability information from both devices, determines the appropriate transmission target, and facilitates the connection information transfer. This mediator eliminates the need for user intervention in authentication and setting processes, achieving fully automatic handover while maintaining ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent performs preliminary actions by acquiring capability information from control target devices before the actual handover process. The intermediary device determines in advance which device can receive connection information and prepares the transmission target selection beforehand. This preliminary capability assessment enables seamless automatic switching without requiring user awareness during the critical handover moment.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If existing handover technology is used, then communication between devices with matching capabilities is enabled, but communication fails when one device lacks processing capability

Engineering Contradiction:
Improvecommunication success rateVSAvoidcompatibility with different device capabilities
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements feedback mechanisms by having the intermediary device acquire capability information from control target devices and use this information to determine the appropriate transmission target. The system receives feedback about device capabilities and adjusts its behavior accordingly, selecting only devices that can properly process the connection information. This feedback-driven approach ensures reliable communication while adapting to various device capability configurations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent changes the parameter of capability assessment by introducing capability information acquisition as a prerequisite for handover. Instead of assuming all devices can process connection information, the system evaluates the capability parameter of each device and bases transmission target selection on this evaluated parameter. This parameter-based selection approach enables both reliability and adaptability across diverse device configurations.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If capability information is not verified, then handover process is simple, but connection information may be transmitted to incompatible devices

Engineering Contradiction:
Improvehandover process complexityVSAvoidcompatibility verification
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent performs capability information acquisition and transmission target determination as preliminary actions before the actual connection information transmission. The intermediary device gathers capability information, analyzes compatibility, and identifies the appropriate transmission target in advance. This preliminary verification process, while adding some complexity, ensures that connection information is only transmitted to compatible devices, thereby maintaining high reliability without requiring complex verification during the critical transmission phase.

Inventive Principle:
Principle #10Preliminary action
